215 215

222 -The purpose of the decoder function is to parse the incoming data and metadata to a format that ThingsBoard can consume.
221 +Once Thingseye receives this message, it forwards this payload to the matching device through the integration.

271 += 7. Creating a Dashboard =
272 +
273 +Thingseye **Dashboards** provide a powerful way to visualize and monitor real-time and historical data from connected devices. They allow users to create interactive, customizable panels displaying telemetry data, device status, and other key metrics. With a variety of widgets, including charts, maps, and tables, dashboards help users gain insights, track trends, and manage IoT deployments efficiently.
274 +
275 +This section guides you on how to create a dashboard to display temperature and humidity data from the device on a time-series chart. You may also use other widgets in Thingseye to display data according to your requirements.
276 +
277 +First simulate a few messages using MQTT. This time, we have added the 'humidity' field to the payload. Eg:
